350.org

What 350.org does

350.org is a 501(c)(3) non-profit climate advocacy organization founded in 2008 by Bill McKibben and headquartered in Boston, Massachusetts, with operations spanning 188+ countries. The organization operates a grassroots movement-building model that connects 490+ active local climate groups across 29 staff countries to organize mass public actions, online campaigns, and policy advocacy aimed at ending fossil fuel expansion and accelerating a transition to renewable energy. Core activities include fossil fuel divestment campaigning, direct mobilization against fossil fuel infrastructure projects, training of grassroots organizers, and influencing international climate negotiations including the UNFCCC COP process. Leadership is provided by Executive Director Anne Jellema, with McKibben serving as Founder and Senior Advisor alongside co-founders Blair Palese and Will Bates, who remain in active campaign leadership roles.

The organization's technology stack consists of digital campaign infrastructure including a main website at 350.org, an online organizer training platform at trainings.350.org, a climate storytelling community at stories.350.org, and a merchandise storefront at 350store.org. These platforms support its named campaign products including The Great Power Shift, Draw the Line, Our Own Power Network, Global Power Up, and Powerlines not Pipelines. The organization does not develop proprietary AI or advanced technology; its competitive differentiation stems from scale of mobilization (1.3M+ people mobilized in 2025), a coalition network of 260+ allied organizations through efforts such as StopEACOP, and brand recognition built over 17 years of climate organizing.

350.org funds its operations through individual donations, which comprised 54% of FY2025 revenue ($9.046M), and grants from foundations, which comprised 47% ($7.961M), with named funders including Ford Foundation, Oak Foundation, Rockefeller Family Fund, Schmidt Family/11th Hour Project, European Climate Foundation, and Oxfam Novib. Total revenue declined from $19.689M in FY2024 to $16.884M in FY2025, a 14% decrease that triggered staff layoffs and program restrictions. The organization employs 164 permanent staff globally.
